Information required by E.P.A. (US)
The level of noise entering a person's ear, when hearing protector is worn as directed, is closely approximated by the difference
between the A weighted environmental noise level and the NRR.
Example:
1. The environmental noise level as measured at the ear is 92 dBA.
2. The NRR is 25 decibels (dB).
3. The level of noise entering the ear is approximately equal to 67 dB.
Caution. For noise environments dominated by frequencies below 500 Hz the C-weighted environmental noise level shall be
used. Warning. Improper fit of this device will reduce its effectiveness in attenuating noise. Although hearing protectors can be
recommended for protection against the harmful effects of impulsive noise, NRR is based on the attenuation of continuous noise
and may not be accurate indicator of the protection attainable against impulsive noise such as gunfire.
